ASME SB163 Monel 400 (N04400) Nickel Alloy Tube Embedded G Type
Embeded Fin Tube
Monel400 alloy (UNS N04400,2.4360) is a single-phase solid solution Ni-Cu
alloy based on nickel, which can withstand various corrosive
environments and has good ductility.It has good corrosion
resistance in many media environments. From a slight oxidizing
medium environment to a neutral environment to a suitable reducing
environment, it has good corrosion resistance. It has a long
history as a corrosion-resistant material.Monel400 alloy is also
used in underwater environments and non-oxidizing chloride
solutions.
Monel 400 Features:
Monel400 is a kind of corrosion resistant alloy with large amount,
wide application and excellent comprehensive properties. This alloy
has excellent corrosion resistance in hydrofluoric acid and
fluorine gas medium, and also has excellent corrosion resistance to
hot concentrated lye. At the same time, it is also resistant to
corrosion of neutral solution, water, seawater, atmosphere, organic
compounds, etc. An important feature of the alloy is that it
generally does not produce stress corrosion cracks and has good
cutting performance.
Corrosion resistance:
The corrosion resistance of Monel400 is generally better than
nickel copper, it is more resistant to the corrosion of reducing
media than pure nickel, and is more resistant to the corrosion of
oxidation media than pure copper, and has very good corrosion
resistance to sulfuric acid, phosphoric acid and carbon. In
particular, it is resistant to the corrosion of hydrochloric acid
and has excellent corrosion resistance to hot concentrated alkali.
Monel400 alloy has excellent corrosion resistance in fluorine gas,
hydrochloric acid, sulfuric acid, hydrofluoric acid and their
derivatives. At the same time, it is more resistant to corrosion in
seawater than copper-based alloys. Monel400 is a deformable
nickel-copper nickel-based alloy with good seawater corrosion
resistance and chemical corrosion resistance, and strong resistance
to chloride stress corrosion cracking. This alloy is one of the few
alloys that can be used in fluoride. It has good oxide resistance
in hydrofluoric acid and fluorine gas medium
